A Florida man reportedly fatally stabbed his boss because the man took a picture of him and posted it online, according to NBC 6 Miami.

Tilus Lebrun, 36, was arrested Thursday and charged with first-degree premeditated murder and murder while engaged in a certain felony offense. He was ordered held without bail until his arraignment.

Police say Lebrun told them he killed his boss because the man, Dimitrios Karaloukas, 61, owner of the Jimmy the Greek Taverna in Boca Raton, Fla., photographed him and posted the picture online.

On Thursday, witnesses told police that Lebrun walked into the restaurant’s dining room, where the popular restaurateur was sitting, and stabbed him repeatedly in front of horrified diners. Lebrun allegedly then stabbed an unidentified co-worker several times before fleeing the scene. Karaloukas later died from his injuries, and the co-worker was taken to Delray Medical Center in Delray Beach.

Police say they captured Lebrun about a block away from the restaurant, still wearing his work apron and holding the knife.
